"Desmond installed glass block in the basement window well to replace a leaking casement window. He quickly returned my call for an estimate and gave me a quote upon inspection. He installed the glass block perfectly along with waterproofing and even did an extra coating of mortar on the outside sill so that water would slope away from the window. The work was done expertly. I would highly recommend Desmond - he is very nice person, knowledgeable and performs stellar work."

"I highly recommend Fabiano's Construction. Our experience with him was fantastic from beginning to end. The project was to restore and replace the exterior window frames of our 1830 Trinity. The previous owners had installed new windows on the inside but left the old ones outside for beauty. Many of these old windows were completely rotten at the bottom, barely holding the small panes of glass together. We got three estimates. One builder wanted to replace the old windows with a second set of new ones. Another was going to patch them up with wood filler. Fabiano was the only one who was willing to actually restore them, using green wood for the parts that were beyond salvaging. It was precision carpentry work requiring problem-solving ingenuity. The new frames and sills are green wood plus Azek (PVC), so they should last forever. Although more major restoration was necessary than foreseen, Fabiano and his crew—his son Will and assistant Simon—still finished the job in the predicted time. They were careful, focused, hard-working, and also really nice, honest people. It was a pleasure to meet them, and the result is a stunning improvement to our house both inside and out. Fabiano is responsive and friendly, an expert who takes pride in his work. Incredibly, his price was the lowest the three. We plan to hire him for another project."

Glass Block questions, answered by experts

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line. 

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

Although glass block windows are made of multiple layers of thick glass, they can still break. If an individual block shatters, it can be removed and replaced, but this is a job for a window repair professional. The project is often complex and may require breaking the block further for removal. Do not attempt to handle it yourself, as the broken glass can be dangerously sharp. A professional will have the necessary tools and expertise to replace the broken glass block quickly and safely. Before hiring, confirm that the repair pro has experience with this specific type of window.
